Abstract
This article describes experimental strategies for cloning or identifying genes encoding DNA-binding proteins. DNA-binding proteins are most commonly identified by electrophoretic mobility-shift assay (EMSA) or DNase I footprinting. To identify the gene encoding a protein detected by EMSA or DNase footprinting, the protein often needs to be purified and its sequence analyzed, as described here. Other methods are also available which do not resort to protein purification, including the one-hybrid screen, in vitro expression library screen, and mammalian expression cloning. These methods are outlined, and their advantages and disadvantages are discussed.
